Filter paper dispenser

ABSTRACT

This invention relates to a filter paper dispenser so designed that with ease of attachment to a smoke spot tester, a ready supply of clean, indexed, and calibrated filter paper is quickly available for smoke spot testing.

BACKGROUND OF THE INVENTION

Particular difficulty has been found .Iadd.with various present brandsof smoke spot testers and their use thereof .Iaddend.in the presentmethod of spot testing the smoke content in the flu pipe of an oilburner. Namely, that the filter paper in common use today is in stripform .[.and.]..Iadd.. The strip is .Iaddend.obtained by the techniciantearing off a useable piece of paper from a serrated sheet to form auseable strip. Herein lies one of the difficulties. Usually thetechnician making the test has either serviced the oil burner or hadmade an inspection. As a result has hands are quite often covered by aquantity of soot, oil dust, and etc,. inherent with and generally foundaround an oil burner. Hence, the moment he selects a filter strip heimparts a print or smudge from his hands onto the filter paper evenbefore he makes a test. This contamination can degrade the test data andlead to erroneous conclusions. Also, the concept of placing a smallstrip of limp paper in a narrow slot is awkward, and difficult and oftenfalls out and onto the floor where it is further dirtied.

Another difficulty of importance is that after a spot test has beenmade, the test strip of filter paper must be moved or removed from thespot tested for inspection. In so doing, the test paper can be easilydropped, further contaminating the test or becoming disorientated. Sinceseveral tests are usually made on one strip a disorientation of the teststrip can be confused with the first test or any other test, dependingon how the paper was moved after each test.

SUMMARY OF THE INVENTION

The object of my invention is to provide .Iadd.a paper dispenser thatwhen attached to a smoke spot tester, will provide .Iaddend.an immediatesupply of clean filter paper calibrated and indexed for identification.These features can be more clearly understood when considered inconjunction with the accompanied drawing.

DETAILED DESCRIPTION OF THE INVENTION

.[.The.]. .Iadd.With reference to FIG. 1, the .Iaddend.dispenser iseasily attached to a standard spot tester with two set screws 1 whichare pre-assembled to the support bracket 6. A one time alignment of thepaper slot 5 with a standard spot smoke tester is necessary and easilyachieved. The dispenser can 4 is pre-loaded with approximately 15 (moreor less) feet of paper 7 providing a sufficient supply for many tests.The filter paper 7 is moved and handled only on the edge protruding fromthe spot tester, its movement being in increments as determined by thenumbers on the paper 7. After a test is complete the strip can be pulledout for overall inspection and the gray density of the test spot 9 canbe compared with reference repeating gray scale #8 and separated fromthe remainder of the roll within the container 4 by using the serratedcutting edge 11 within the container 4 by using the cutting edge 11. Theadvantage of the test spot 9 under an indexing number 10 is apparent aseach test is ready for identification, even though the paper might bedropped or become disorentated.

Having now described my invention, I claim:
 1. A dispenser for filterpaper comprising a housing for enclosing a roll of strip material, thehousing having two parallel end walls, two parallel side walls, a bottomportion integrally connecting said walls, and a removable top, one ofsaid end walls having a slot running from said bottom portion to saidremovable top, ring like bracket means attached to said one of said endwalls adjacent the slot for encircling a portion of a smoke tester, anda serrated cutting edge on said bracket means, said edge being parallelto said slot and spaced from said housing. .Iadd.
 2. A dispenser forfilter paper comprising a housing for enclosing a roll of stripmaterial, said housing having bottom and wall portions and a removabletop portion, a slot in said wall portion, means connected to said wallportion adjacent said slot for attaching said housing to a smoke tester,and a cutting edge on said attaching means, said edge being parallel tosaid slot and spaced from said housing. .Iaddend.
